26 Almost all patients with estrogen-receptor positive breast cancer, whether they also receive chemotherapy or not, are advised to consider anti-estrogen therapy ( hormone therapy, endocrine therapy ) to reduce their risk of recurrence Tamoxifen was the standard of care in younger (premenopausal) women Aromatase inhibitors became the standard of care in older (postmenopausal) women in 2001
